nterstate Concrete Pumping in French Camp, CA is using the Con Forms 18-3 SPIDER© Placer to pour the foundation and parking decks for the 75-storey Oceanwide Center high-rise tower in San Francisco, CA. These pours offered a number of challenges unique to high-rise projects –primarily that the footings start 70-feet below street level to provide the support needed for such massive structures. This presents obstacles for the efficient placement of concrete from the street level, high above. Even with large booms that could reach the base, there are substantial issues with maneuverability to effectively and efficiently reach all areas, such as countless walls and columns. Forms, columns, shoring, and other obstacles already in place would make the pour nearly impossible using a typical placing boom or the boom truck from above. Interstate turned to Con Forms for a solution. The solution; a self-propelled 18-3 SPIDER Placer on tracks, with an 18-metre (60-foot) reach to quickly and accurately place concrete. The 18-3 SPIDER© is a cost-effective and low-impact alternative to tower-mounted placing booms, and in this case, a great alternative to dragging long lengths of hose on the mats. Unlike its large-scale cousins, the rugged, compact, and self-propelled 18-3 SPIDER© offers versatility and low jobsite impact with the same productivity. The crane capacity and shoring requirements are drastically decreased due to the low overall unit weight, and the SPIDER© unit requires minimal site preparation prior to placement. The lightweight Con Forms 18-3 SPIDER© Placer was lowered by crane into the 70-foot-deep hole in downtown San Francisco to pour the base for the 75-storey skyscraper. The self-propelled, tracked placer unit was able to easily maneuver around the founda-
